Degenerative joint disease in Great Moravian population from the locality Mikulčice - Valy
Müllerová, Soňa ; Brukner Havelková, Petra (advisor) ; Stránská, Petra (referee)
This diploma thesis had two primary objectives. The first one was to examine if the incidence and development of primary degenerative joint disease (DJD) of the joints of the vertebral column and the limbs in an early medieval population from a cemetery by the sixth church in Mikulčice were affected mainly by the skeletal age of the deceased, or if other factor of physical loads was more significant. A set of 83 skeletal remains was evaluated primarily by Waldron's method (2009), but methods by Stloukal and Vyhnánek (1976); Buikstra and Ubelaker (1994); and Sager (1969) were also used. Schmorl nodes and eburnation were tracked too. Evaluated were vertebral joint (both intervertebral and apophyseal), jaw and limb joints. The results indicate that the incidence of degenerative joint disease in intervertebral joints, temporomandibular joint and appendicular joints is significantly affected by age, with the onset of degeneration being after the 40th year of skeletal age. No correlation of incidence of Schmorl nodes with age was present, and only a few cases of eburnace were noted. The relationship between the presence of DJD and the sex of the skeletons was not approved. I have compared these results with those from similar studies. I have deemed the primary evaluation by Waldron's method to be good...

Degenerative joint disease in bioarcheology
Müllerová, Soňa ; Velemínský, Petr (advisor) ; Kuželka, Vítězslav (referee)
This thesis is divided into three parts. The first part aims to summarize the basics of etiology - issues of degenerative joint disease (DJD), firstly from the medical point of view and subsequently from the perspective of bioarchaeology. The next chapter offers a list of assessment options for degenerative joint disease in large axial joints and the spinal joints. It describes 10 methods used for assessment of DJD in axial joints, 13 methods for intervertebral joints and 4 methods for apophyseal joints. In the last part, there are examples of degenerative joint disease cases observed in a population-based study of human skeletal remains uncovered in the domain of today's Czech Republic. The main aim was to create a summary of incidence of this disease from the Bronze Age to present. Considering the fact that all hitherto carried out studies in this field were merely realized in large population groups with good preservation of skeletal remains, only studies of skeletal remains dating back to the early Middle Ages were selected (Mikulčice- Valy, Kostelisko, Josefov). Therefore, only the incidence of DJD in the mediaeval population could have been described. In other prehistoric and historic eras the degenerative joint disease cases were not assessed in detail, by the epidemiological approach or...

Modelling potential distribution of invasive plants Indigo bush (Amorpha fruticosa) and Goji berry (Lycium barbarum) in the Czech Republic
Müllerová, Soňa ; Moudrý, Vítězslav (advisor) ; Barták, Vojtěch (referee)
Biological invasions are currently considered to be one of the major threats to biodiversity. Invasive species are introduced species naturalized in regions outside their native range with both ecological and economic impact known from many regions all over the world. In the Czech Republic, vascular plants constitute a major group of invasive species. They are characterized by the ability to adapt, spread and occupy new sites. Early identification of potentially dangerous species constitute a possible way to prevent further spread. This bachelor thesis presents the use of species distribution modelling technique as a tool for assessing invasive potential and predicting species invasions. The aim was to create the model of invasive shrub species Indigo bush (Amorpha fruticosa) and Goji berry (Lycium barbarum) potential distribution in the Czech Republic and explore the significance of each predictor variable including variables derived from digital elevation model. Models were created in the resolution of 100 m using Maxent method based on presence-only data and ten predictor variables including three topographic variables: elevation, slope and aspect. The results show that the most significant variables for both species are elevation, land cover which is the most important one for Amorpha fruticosa, and temperature annual range. Slope variable is significant for Lycium barbarum. Aspect is not significant. In terms of AUC discrimination measure, high values were achived for both species. AUC value for Amorpha fruticosa is 0,961 and 0,906 for Lycium barbarum. However, the realism and quality of the model is significantly influenced by the stage of invasion and also by complexity and accuracy of input data.
